I have a category ID and wan't to display all the subcategories. Show should I do that in Joomla?
I've tried the following
$catID = JRequest::getVar('id');
$categories = JCategories::getInstance('Content');
$cat = $categories->get($catID);
$children = JCategoryNode::getChildren($cat);
printObject($children);
But it doesn't work.
getChildren is not a static function, you call it off the category object that you get from get, which should be of type JCategoryNode.
$catID = JRequest::getVar('id');
$categories = JCategories::getInstance('Content');
$cat = $categories->get($catID);
$children = $cat->getChildren();
print_r($children);
